While the bottle itself is a great concept for those serious about hydration it leaves a bit to be improved upon. First, the lid needs to turn another 1/4 turn. They way then lid sits it's impossible to you the molded handhold to drink because the spout is in the wrong location, which means unless your hands are oversized you need to use 2 hands to drink out of it. Second, the straw feature seems to be an after thought. The straw only comes 1/3 of an inch over the spout so you have to pull it up each time you want to take a drink. And, you can not close the lid with the straw in the bottle. And third, after only 6 days the lock for the cap snapped so it no longer locks closed.
